The Digitized Sky Surveys were produced
at the Space Telescope Science Institute under U.S. Government
grant NAG W-2166. The images of these surveys are based on photographic
data obtained using the Oschin Schmidt Telescope on Palomar Mountain
and the UK Schmidt Telescope. The plates were processed into the
present compressed digital form with the permission of these institutions.

The National Geographic Society - Palomar
Observatory Sky Atlas (POSS-I) was made by the California Institute
of Technology with grants from the National Geographic Society.

The Second Palomar Observatory Sky Survey
(POSS-II) was made by the California Institute of Technology with
funds from the National Science Foundation, the National Geographic
Society, the Sloan Foundation, the Samuel Oschin Foundation, and
the Eastman Kodak Corporation.

The Oschin Schmidt Telescope is operated
by the California Institute of Technology and Palomar Observatory.

The UK Schmidt Telescope was operated by
the Royal Observatory Edinburgh, with funding from the UK Science
and Engineering Research Council (later the UK Particle Physics
and Astronomy Research Council), until 1988 June, and thereafter
by the Anglo-Australian Observatory. The blue plates of the southern
Sky Atlas and its Equatorial Extension (together known as the
SERC-J), as well as the Equatorial Red (ER), and the Second Epoch
[red] Survey (SES) were all taken with the UK Schmidt.
